How to Configure Dhcp In Cisco Routers

DHCP provides configuration parameters to Internet hosts. DHCP consists of two components: a protocol for delivering host-specific configuration parameters from a DHCP Server to a host and a mechanism for allocating network addresses to hosts. DHCP is built on a client/server model, where designated DHCP Server hosts allocate network addresses and deliver configuration parameters to dynamically configured hosts. By default, Cisco routers running Cisco IOS software include DHCP server and relay agent software.

DHCP supports three mechanisms for IP address allocation:

•Automatic allocation—DHCP assigns a permanent IP address to a client.

•Dynamic allocation—DHCP assigns an IP address to a client for a limited period of time (or until the client explicitly relinquishes the address).

•Manual allocation—The network administrator assigns an IP address to a client and DHCP is used simply to convey the assigned address to the client.

Router Commands : 


Router#configure terminal 

Router(config)#interface fastEthernet 0/0

Router(config-if)#ip address

Router(config-if)#no shutdown 


Router(config)#ip dhcp pool admin





Router(config)#ip dhcp excluded-address
